Content, Learning Outcome and Preconditions
This course is the first part of a series of two, dealing with the physical principles of magnetic resonance imaging. The second part of this series is described accurately in the module PH2271.
The content of the first part focusses on the principles of magnetic resonance(MR) image formation. The lecture starts with addressing the question how an MR signal is generated, continues with the detection and manipulation of this signal and will finally cover the details how MR signals are processed into an image.
Specifically, we will focus on:
1. Introduction to MRI
2. MR signal generation
a. Magnetic moments
b. RF excitation
c. Signal detection
3. MR signal characteristics
a. Free induction decay
b. Spin echo
c. Gradient echo
4. Spatial encoding of MR signals
a. Slice selection
b. Frequency and phase encoding
5. Relaxation and image contrast
a. Saturation-recovery sequence
b. Inversion-recovery sequence
c. Spin-echo sequence
After successful participation in this module the student is able to
- describe the physical principles underlying the process of MR signal generation and detection.
- understand how an MR image is generated.
- explain how signal contrast in an MR image is produced.
- analyze MR pulse sequences and understand how they work.
No preconditions in addition to the requirements for the Master’s program in Physics.
Courses, Learning and Teaching Methods and Literature
Learning and Teaching Methods
Oral presentation, Quiz, Exercises, Discussions.
Physics of Magnetic Resonance Imaging I has 5 homework problem sets. Homework will be handed at the end of selected lectures. In the beginning of the next lecture, the students are able to hand in their solutions, which will not be graded. The solutions of the homework problems will be discussed in class during the first hours of the class when the homework is due.

Description of exams and course work
There will be a written exam of 60 minutes duration. Therein the achievement of the competencies given in section learning outcome is tested exemplarily at least to the given cognition level using calculation problems and comprehension questions.
For example an assignment in the exam might be:
- How is a 2D or 3D image encoded?
- How can T1 contrast be introduced in a gradient echo sequence?
- Calculate, how many protons effectively contribute to the generated effective magnetic moment in a magnetic field of 7 T.
In the exam no learning aids are permitted.
There will be a bonus (one intermediate stepping of "0,3" to the better grade) on passed module exams (4,3 is not upgraded to 4,0). The bonus is applicable to the exam period directly following the lecture period (not to the exam repetition) and subject to the condition that the student passes the mid-term of handing-in at least 3 of 5 homework set sheets.
The exam may be repeated at the end of the semester.
